<p><P>PROBLEM TO BE SOLVED: To resolve problems wherein, in desulfurization of sulfur-containing flue gas generated in combustion of coal, a limestone-gypsum method requires power and a large amount of water for circulation of slurry causing enlargement and complication of the desulfurization facility, while in an adsorption method by activated carbon, a large amount of heat is needed for heating sulfur content adsorbed in activated carbon for decomposition and recovering, also causing enlargement and complication of the facility. <P>SOLUTION: High efficiency of the whole of the desulfurization system, durability, economic performance, easiness in maintenance and management of the desulfurization facility can be obtained, by combining a wet type ammonia absorbing method with a dry type activated carbon and alkaline absorption method. <P>COPYRIGHT: (C)2007,JPO&INPIT</p> |
